Describe to me the difference between validation and verification.

Answer posted by Radhika on 2005-05-24 08:29:43: Verification takes place before validation, and not vice versa. Verification evaluates documents, plans, code, requirements and specifications. Validation evaluates the product itself. The input of verification are checklists, issue lists, walkthroughs and inspection meetings, reviews and meetings. The input of validation is the actual testing of an actual product. The output of verification is a nearly perfect set of documents, plans, specifications and requirements

Verfication: ofcourse this is the process before validation. It means to check whether a given software is having all the features as written in the specification document. say I am building a MP3 player, so features may be like play, pause, forward, reverse. So if all the four features are there then my verfication is complete.

Validation: validation is to check whether those features work as supposed to work. as in above given example whether Play is working correctly. when I press reverse whether song reverses??? so in nut shell to check whether features are working correctly.

Difference between Verification and Validation:Verification takes place before validation, and not vice versa. Verification evaluates documents, plans, code, requirements, and specifications. Validation, on the other hand, evaluates the product itself. The inputs of verification are checklists, issues lists, walkthroughs and inspection meetings, reviews and meetings. The input of validation, on the other hand, is the actual testing of an actual product. The output of verification is a nearly perfect set of documents, plans, specifications, and requirements document. The output of validation, on the other hand, is a nearly perfect, actual product
